Specification of Letters Patent.

Application filed February 16,1916. Serial No. 78,619.

To all whom it may concern:

Be it known that I, WALTER R. PATTER- SON, a citizen of the United States, and a resident of Thief River Falls, in the county of Pennington and State of Minnesota, have invented a new and Improved Double- Acting Non-Sagging Door-Hinge, of which the following is a full, clear, and exact description.

This invention relates to door hinges of the double-acting type inwhich the door and jamb leaves are connected by the sections of an intermediate or central leaf for permitting the door to swing in either direction.

The invention has for its general objects to improve the construction of hinges of this type so as to be reliable and eflicient in use, comparatively simple and inexpensive to manufacture and so, designed as to produce the self-closing of the door hung by the hinge.

A more specific object. of the invention is the-provision of a simple,.novel and effective double-acting, non-sagging door hinge having an improved arrangement of springs for causing the automatic closing of the door, the spring means being so designed'that the tension-can be easily and quickly adjusted and the parts easily and quickly assembled in'the manufacture of the hinge.

WVith such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction andarrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a front view of'the door hinge with the parts in 'the position they occupy when the door is fully open, and portions being shown in section to illustrate details; Fig. 2 is a plan view of the hinge and representing by dotted lines the door section as havingbeen moved through one hundred and eighty degrees to the left or ninety degrees to the right; Fig. 3 is a perspective view showing the leaves and spring barrels of the hinges disconnected; Fig. 4 is a detail sectional view on the line 4-4, Fig. 1; and Fig. 5 is a plan view of one of the springs of the hinge.

Referring to the drawings, A and B designate the main or outer leaves of the hinge, which leaves are adapted to be connected respectively with a door jamb and a door, and C and D are the sectional intermediate leaves which connect the outer leaves A and B together. The outer leaves have apertures '1 to receive screws'for fastening them to the door and door jamb. From one sideedge of the leaf A'are pintle receiving ears 2, and at the opposite'edge are ears 3, the latter being'arranged closer to- 'gether than the ears 2 and'at the lower end of the leaf, while the ears 2 are-adjacent the upper-end. The leaf A has laterally extending horizontal flanges a which have arcuateouter faces 5 to form rocking surfaces on which the other outer leaf B is adapted to bear, whereby slack or-lost'motion is prevented when thedoor is in closed position. The leaf B hasears '2 atone edge and 3 -at the opposite'edge. The upper inner section C has pairs Ofapertured ears 4 and 5 extending respectively from opposite edges to coeperate with theears2-and 2 of the outer leaves, and-the lower intermediate section D has pairs of ears 6'and 7 extending from opposite edges, which cooperate with the ears 3 and 3* of the outer sections. A pair of pintles 8 and 9 connect the intermediate upper section C with the right and left edges of the outer sections A and B, assuming the hinge to be closed, as in Fig.2, and pintles .10 and 11 connect the-lower intermediate section D with the right and left edges of the outer leaves A and B. In other words,the pintle 8 passes through the ears 2 and 4,. and it willbe noted that the ears 4 rest ontop of the ears2 in alternate disposition. The'pintle 9 passes through the ears 2 and 5 andthe ears'p2 rest on the ears 5 in alternate disposition. The pintle '10 passes throughthe ears'3 'and (land the ears 6 rest on the ears 3 and alternate therewith. Thepintle llpasses through the ears 7 and 3 with the latter resting on the ears 7 and alternatingtherewith. The pintles 8 and 9 are inserted upwardly into the ears, and the upper ends are. threaded to receive knob nuts 12. The pintles 10 and 11 are inserted in the ears downwardly and have knob nuts 13 screwed on their lower ends.

In order to make the door self-closing, a

, set of helical springs 14 and 15 encircles each of the upper pintles, and both sets are connected with the upper intermediate section C and with the sections A and B, so that the door can be opened in either direction and swung closed. Each set of springs is arranged in a circular barrel 16 which has a head 17 at one end and at this headed end are apertures 18 and 19 at diametrically opposite points for receiving the outwardlybent extremities 20 and 21 of the springs. The springs have their opposite ends ex tending into a chamber 22 of an ear 2 on the leaf A and an ear 2 on the leaf B, and these chambered ears have apertures 18 and 19 for receiving the extremities 20* and 21 of the springs 14: and 15. These springs are inserted and their extremities interlock with the barrel and hinge ears before the pintles are inserted, and it will be noted that the springs are of different diameter so that one lies concentrically within the other. The barrels 16 are adapted to be adjustably interlocked with the intermediate leaf C and for this purpose the headed ends of the barrels have peripheral notches 23 into which engage locking pins 24L slidable in horizontal openings 25 in the leaf C. These openings 25 are drilled in from the opposite edges and behind each locking pin 2 1 is a spring 26 which urges the locking pin outwardly, but when the parts are assembled the barrels hold the locking pins in place. The notches 23 are formed with cam surfaces 27 so that by the turning'of the barrel for the tightening of the springs the locking pins ratchet past the notches. It will thus be seen that the tension of the springs can be easily and quickly adjusted without the use of any implements.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

Copies oi this patent may be obtained tor five 1. A hinge comprising outer leaves, upper and lower intermediate leaf sections, a pair of pintles respectively connecting the upper section with the right edge of one outer leaf and the left edge of the other, pintles respectively connecting the lower intermediate section with the left and right edges of the said outer leaves, barrels rotatably mounted on one set of pintles and having notches,

spring-pressed pins on one of the intermediv ate sections and engageable in the notches of the barrels to prevent rotation thereof except in one direction, a set of springs in each barrel and each having an end connected therewith, and connections between each set of springs and an outer leaf.

2 A hinge including outer leaves, an intermediate leaf, ears on the leaves, pintles passing through the ears and connecting the leaves together, the intermediate leaf having spring-pressed pins projecting from opposite edges, barrels on the pintles, means on the barrels engageable by the pins for preventing the barrel from turning except in one direction, helical springs of different diameters concentrically arranged in the barrels and encircling the pintles, means connecting one end of each spring with its inclosing barrel, and means for connecting the opposite end of each spring with an outer leaf.

3. A hinge comprising outer leaves, upper and lower intermediate leaf sections, a pair of pintles respectively connecting the upper section with the right edge of one outer leaf and the left edge of the other, pintles respectively connecting the lower intermediate section with the left and right edges of the said outer leaves, spring means between the upper intermediate section and the outer leaves for insuring the self-closing action of the hinges, and horizontally extending flanges projecting from one of the outer leaves and each having an arcuate outer edge forming a bearing for the other outer leaf.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
